PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 260,792, dated July 11,1882.

Application filed May 4, 1881.

ters Patentofthe United States No. 168,635,

granted to Griffith and'Byrne, October 11, 1875 and it has for itsobjectto increase the form capacity without materially adding to thesize of the press, and to cause the ink-rollers to properly travel overthe form andink-distributing surface. The form-bed, instead of being aplane cut from a cylindrical body, is a plane forming one of the sidesof a flattened body, and the ink-rollers are caused to roll'.'

movement by cams formed'on the ends of the. flattened body, and whichare driven by means.

of suitable moving connections attached to the gear-wheels running onbearings provided therefor at the ends of the stationary flattened body,said gear-wheels being actuated from the driving-shaft of the press bymeans of wheels orpinions thereon, all of which will be 'fullyunderstood by reference to the accompanying drawings, forming part ofthis specification, in which Figure 1, Sheet 1, isa front elevation ofmy improvements in printing-presses. Fig. 2, Sheet 1, is a sideelevation of the same. Fig. 3, Sheet 1,is an end view of the flattenedbody, showing the ink-rollers in different positions. Fig. 4, Sheet 1,is a sectional view out through one of the ink-roller carriers. Fig. 5,Sheet 2, is an'end elevation of a modificatiompartly in section. Fig. 6,Sheet 2, is a front elevation of the same. Fig. 7, Sheet 2, is acentralsection of one of the roller-carriers enlarged; and Fig. 8, Sheet 2, isa plan view of the same.

Referring to Figs. 1, 2, 3, and 4, the flattened (ModeL) body a, whichforms the type-bed a and inkdistributing surface a is rigidly secured inposition by its end hubs fitting into recesses on the tops of the sideframes, 1) b.

The ink=roller carriers, of which there is one at each end of theflattened body for each pair of ink-rollers, consist of the piece 0,provided with the roller d, arranged to bear against the internal faceof the flange-cam 0, formed at each end of the body a, and the plate f,provided with a lug which fits into arectangular opening in the piece 0,and two lugs, f,which bear against the sides of the piece 0, leaving theplate f and piece 0 free to move up and down in relation to each other;but they are "prevented from separating laterally by the grooved rollerg, which rotates on a stud secured in the lug of the platef, which fitsinto the rectangular opening in the piece 0.

p The end journals of the ink-rollers h it work in open bearings in theplate f, as shown in Fig. 2, and they are held against theinledistributin g surface a and the faceof the type,

which would be held in a chase slipped down I the inside of the flanges(shown in Fig. 1) at the ends of the type-bed a, by means of a spiralspring, '5, placed between the top of the lug on plate f in therectangular opening of the piecec and the upper side of saidopening,which spring at the same time holds theroller 01 against theinternal face of the came; and, referringto Fig.3, it will be seenthatthe internal face of the camflange e is so shaped in relation to theoutside of the body a that the ink-rollers h h and roller 01, when incontact with their respective bearing-surfaces, maintain the samerelative position to one another in Whatever part of the body a they maybe, as illustrated by the dotted similar and equal-sized trianglesconnecting the centers of the three sets of circles, 72. h d, h 7811*,and 71, 71. 01 so that there will be no movement imparted to the spring2' as the ink-rollers h h are perfectly cylindrical, in

a which case the screw 1, which passes through the top of the piece 0,can be set down so as to touch the top of the lug on the plate f, thusvirtually making piece 0 and plate f solid; but I prefer under ordinarycircumstances to leave a little space between the ends of the screws andthe lugs, and to keep the ink-rollers to their work by means of thesprings 2' i.

To remove and replace the ink-rollers h h, the screws l are backedsulficiently to allow the plates f to be raised against the action ofthe springs 'i, so that the open bearings in the plates f leave thejournals of the rollers h free.

The ink-roller carriers at both ends of the body a are alike, and theremay be any number of them necessary to hold the required number ofink-rollers, one pair only and two pairs of ink-rollers being shown inthe drawings. They are caused to revolve around the body a by thegrooved rollers g, fitting into flanged radial grooves in m on theinside faces of the gear-wheels or drivers at n, rotating on the hubs ofthe body a and driven by the gear wheels or pinions n, secured to thedrivingshaft it.

Instead of the grooved roller 9, rectangular blocks may be used, adaptedto slide in the flanged radial grooves m m and, instead of the flangedradial grooves m m and grooved rollers g being employed to drive theink-roller carriers, they may be substituted by links connected to themand pivoted to the sides of the gear-wheels n n; and the form of thebody a may be varied-as, for instance, its general formgnay beelliptical, with the flat surface for the typebed a.

or represents a chase holding a form, x, placed in the grooves on thesides of the typebed a. The dotted lines 3 Fig. 2, represent the platenof the press. ts actuating mechanism is not here shown, as I propose touse for this purpose the devices illustrated in the before-mentionedpatent to Griflith and Byrne, No. 16S,635,dated October 11, 1875. Thegearwheels 11 a revolve in the direction indicated by the arrow z. Fig.2.

In the modification shown in Figs. 5, 6, 7, and 8 the main piece 0 ofthe roller-carrier has a dovetail groove in its face, which is adjacentto the cam 0, and in which fits the sliding piece 1). The cam-roller dis pivoted to this slide To hold the carrier in place when theink-rollers h h are removed, I make the cam e a closed cam by formingthe face 0 on the end of the body a.

The slide 12 has a projection, 11, which fits into an opening formed inthe upper end of the main piece 0, and to the top of this projection isattached, by means of a screw, the small half-elliptical spring 1', theends of which bear on the top of the main piece 0 between the lugs, toprevent it jarring out of place when the press is running; and shouldthe spring 1- from any cause break, the main piece 0 is prevented frommoving outward sufficiently to free the journals of the ink-rollers h byreason of it coming in contact with the saddlepiece r.

When it is desired to remove from or replace the ink-rollers in thepress the spring a and saddle r are turned around into a right-angularposition, as shown at Fig. 6, in the upper carrier, which allows themain piece 0 to be raised until the open bearings clear the journals ofthe ink-rollers h.

Two pairs of ink-rollers are here shown, the carriers of each pair beingconstructed as above described, and the main piece 0 of each carrier isconnected to the wheel n by means of the link 8, the one end of thelinks of the two carriers at each end of the body a being pivoted to theside of the wheels at by one stud, as shown at s, so that as the wheel arevolves on the hub of the body a the carriers of the front pair ofink-rollers are pushed around the body a and the carriers of the secondpair are pulled around the body a.

Fig. 5 is an end view of the body and ink roller carriers with the wheelit removed, and Fig. 6 is a front elevation of one end of the body, 850.In Fig. 8 the half-elliptical spring is removed to more clearly show theconstruction of the carrier.

If it is desired to operate the press with only one ink-roller to eachpair of carriers, or with only one pair of ink-rollers, then in place ofthe ink-rollers removed I propose to use plain rods with bearing-rollersthe size of the inkrollers on their ends to cause the carriers to travelaround the cams c, the same as when the ink-rollers are used.

I wish it understood that 1 do not claim broadly ink-rollers adaped tobe rotated around a fixed body which constitutes the type-bed andink-distributing surface, as such is shown in the before-mentionedpatentto Grf'lflillll and Byrne; but

What I claim, and desire to secure by Let ters Iatent, is-

1. As an improvement in printing presses, the stationary body formingthe type-bed and ink-distributing surface, and provided with aflange-cam at each end, ink-roller carriers having eacha roller attachedthereto, adapted to work against theinternal faces of the flan gecams,and open bearings for the ink-rollers, and. rotating wheels on the hubsof the fixed body connected to the ink-roller carriers, substantially asand for the purpose hereinbefore set forth.

2. In a printing-press, a stationary irregularly-formed ink-distributingand chase-holding body, having at each end an irregularlyformedflange-cam, in combination with two ink-rollers and their carriers,provided with bearing-rollers adapted to work on the internal faces ofthe cams and hold the ink-rollers firmly to the periphery of the body inall positions, substantiallyin themanner and for the purposehereinbefore set forth.

3. In a printing-press, in combination, the flattened body a, providedwith the cams e, the ink-roller carriers 0, provided with rollers d, anddrivers n a, connected by moving connections to the ink roller carriers,substanziallily as and for the purposes hereinbefore set 'ort 4. Incombination, the inkrollers h h, plate and the ink-rollers h h, incombination, con- 1', sliding on piece 0, provided with roller 61,spring i, and cam e, substantially in the man: Her and for the thepurposes hereinbefore set forth.

5. The flanged radial grooves m m on driver n, the grooved roller g, theink-roller carrier f c d, cam e on the end of the flattened body a,

manner and for the purpose set forth.
